Question

Please solve with working! much appreciated

Answer 1

i. ) The fraction
`(1.7)/(1.3)` as a number with one decimal place is 1.3.

ii. ) The height of the tree is 37.9 m

Explanation:

One decimal Place:

Some examples,

4.23 ————————- 4.2

97.456 ———————- 97.5

7324.89456 ————— 7324.9

0.95 ————————- 1.0

76 —————————- 76.0

• After the decimal point get rid of all digits but the first 2
• If the second digit is more than 4, increase the first digit by 1
• Always write the decimal point and one digit even if it is zero

Therefore, the fraction
`(1.7)/(1.3)` as a number with one decimal place is 1.3.

ii. )

Given

`(x)/(29) =(1.7)/(1.3) \\x= 29* (1.7)/(1.3)\\x =(49.3)/(1.3)\\x = 37.923....\\x=37.9\ m\ \textrm{rounded to one decimal place}`

Therefore, the height of the tree is 37.9 m
